DINAN STAGE 1 PERFORMANCE ENGINE SOFTWARE - BMW S63 (TU4) ENGINE

Some of the world's most potent sedans and SUVs to begin with, the F90 M5 and F95 X5M now have the ability to go beyond formidable and to levels of outright domination in their respective classes. With max gains on pump gas nearing +130 WHP and +200 lb-ft of torque courtesy of Dinan Stage 1 software the battle for runner-up in each respective class is the only question. Those are garish gains on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive feat. One that will be sure to result in a very enthusiastic grin. Utilize race gas or E85 and the gains jump yet another factor of fun -- a mind boggling +198-226 WHP and +190-207 lb-ft of torque to be exact. While increases in power at this scale typically come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan's calibrations are safe and reliable without sacrificing long-term reliability or performance.

Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labelled as being the smoothest, factory-like solution in the marketplace.
